一、问题的提出在《铁路工程技术规范》(以下简称《规范》)第4—12条规定:“……如出站方向为上坡道时,应考虑出站缓坡,以利于列车起动加速。”但在什么情况下需设缓坡,如何设置加速缓坡,没有具体规定。由于这些地段,一般都是困难地段,需要争取高度,因此,在设置加速缓坡时,就必须认真考虑。 I. PROBLEM PROBLEMS Article 4-12 of “Technical Specifications for Railway Engineering” (hereinafter referred to as “the Code”) stipulates: “...... If the outbound direction is uphill, outbound gentle slope should be considered to facilitate the acceleration of train starting ”However, in any case, it is necessary to set up gentle slope, and how to set the acceleration ramp, there is no specific regulation. Due to the fact that these lots are generally in difficult locations and need to strive for height, they must be carefully considered in setting up the acceleration ramp.
